Force10 S50
FnordNet has a pair of Force10 S50 48 port Gbit Ethernet switches. Thanks, Bryan!
console cable
While there are a bunch of Cisco console cables on hand, Force10 uses a different connector pinout. The console port on the S50 is a female 8P8C modular connector (a normal twisted pair Ethernet connector, often called an RJ45).
The connections on the the console port are as follows. Numbering goes from left to right, looking into the console port connector.
| Pin number | connection | Wire color |
|---|---|---|
| 1 | no connection | white/orange |
| 2 | no connection | orange |
| 3 | RXD - received data | white/green |
| 4 | no connection | blue |
| 5 | no connection | white/blue |
| 6 | TXD - transmitted data | green |
| 7 | no connection | white/brown |
| 8 | no connection | brown |
The other end of the console cable is a DB-9 (or more correctly DE-9) female connector as commonly found on PC serial ports. There are two rows of pins on this connector, the "top" row having 5 connections, the "bottom" row having 4. Facing the connector pins are numbered 5 through 1, left to right, on the top row. Pins 9 through 6 are on the bottom row, from left to right. Here's the connection from the other end of the cable:
| pin | signal | wire color | connected to |
|---|---|---|---|
| 1 | DCD - data carrier detect | any color jumper | pins 6 and 4 on the same connector |
| 2 | RXD - received data | green | pin 6 of opposite end of cable |
| 3 | TXD - transmitted data | white green | pin 3 of opposite end of cable |
| 4 | DTR - data terminal ready | any color jumper | pins 1 and 6 on the same connector |
| 5 | SGD - signal ground | no connect | no connect |
| 6 | DSR - data set ready | any color jumper | pins 1 and 4 on the same connector |
| 7 | RTS - ready to send | any color jumper | pins 8 on the same connector |
| 8 | CTS - clear to send | any color jumper | pin 7 on the same connector |
| 9 | RI - ring indicator | no connect | no connect |
Clearing configuration
These switches arrived used, with unknown configuration applied and with unknown usernames and passwords required to manage them. [SFTOS] is the operating system these switches run, and clearing the switch configuration is accomplished fairly easily:
- Attach the console cable
- Configure terminal program to communicate at 9600bps, 8 data bits, no parity bits, and 1 stop bit.
- Power on switch
- At the prompt
CPU Card ID: 0x508245 Boot Menu Version: 01 Jan 2007 Version 02.01.45 02/07/2007 Select an option. If no selection in 2 seconds then operational code will start. 1 - Start operational code. 2 - Start Boot Menu. Select (1, 2):
- quickly press 2 then Enter.
- At the next menu, select the
Restore configuration to factory defaults (delete config files)option. - Select the
Reset the systemoption from the menu.
